Hard to lose, easy to find

It took me a few minutes to figure out how to use the non contact function properly but it works great. It’s not as sensitive to the touch as other non contact testers but it functions properly. Over utility lines up with the build quality and total value. The plug tester accuracy is also correct. I tested this myself. Not the most durable tester on the market but can be a good replacement from having to carry multiple testers if you work on electrical installs or systems daily.

Works as advertised, no issues!

Quick delivery and works exactly as advertised

I didn't write a review right away as it wouldn't be an accurate feedback to benefit other buyers, as an electrician I depend alot on instruments to do my job, this particular one worked wonderful for a afew months and then... It just died, I tried changing the battery but it didn't work...... So basically I'm giving it 3 stars only on the amount of time it actually worked. I don't know if anyone else had the same problem.

It failed to detect a live outlet after reaching the two-year mark. Replaced a battery, same result.

Worked as intended until this broke today clean off. Now need to go retrieve the broken piece in the socket. Suppose to be testing not taking apart. Thought this was a solid name brand product. Freak accident? I'm confused.

Qualité et prix c’est correct

It is a little more than an electrical receptacal check for correct wiring, and whether the ground fault interruption feature works. It has a voltage sensor that is you hold near a wire you can see if it is "hot" (electrically not temperature). It is a good tool for the more experienced home electricity evaluator. Perspective older home purchasers may want one to check their outlets to make sure there isn't an oops by the previous owners in wiring their outlets. It also might help identify if that stray-wire not connected to anything could electrocute you. However, if you find a problem please contact an electrician to fix it

I own several circuit testers along with multiple multi-meter units. I do like this one for a couple of reasons; 1) it isn't small (which is usually the biggest issue in locating the others. 2) it is easy to grip when testing a receptacle as some of the newer receptacles have built in "child proof" features to impede efforts poke something randomly into them. Multi-meter and short wire leads fail here as you really have to put pressure to work them into the slots.One thing I did initially miss at first was the battery (the L1154F "button" type battery is encased in the plastic packaging on the back. After checking on-line I first looked around the shop to find a compatible button battery (LR44). Installed and used to test the unit for non contact live wires. Another bonus was the button needs to be held down and which initially beeps once to indicate unit is ready for testing. I like this feature as you can then toss the unit into a tool bag without the worry of self draining the battery. This is a common problem with past non-contact pencil testers I own.Overall first impressions are that it is a good solid unit. I'll be wiring a new outdoor prefab tool shed with electricity shortly so I will update this review with other findings of note...

I work as a home inspector and this is my go-to outlet tester because it is easy enough for my clients to read and shows up well in pictures because you don't have to decipher the 3 light codes of the more traditional testers. Green = good. The green light is easier for me read as well and only requires a quick look and then I can move on to the next outlet. It is very efficient with my time. While the non-contact voltage tester is extremely sensitive, it is very helpful in telling me if the wires I am looking at are live or not. It is a little too sensitive though, as it registers hot wires when it is between 1-2" away, so if there are two wires, I can only confirm that at least one of them is live. Not a problem, I keep a higher quality voltage tester in my truck and can go grab it when I need more accuracy. I only need to get my higher quality one about once every 6 months or so, so I'm not dinging this tester for being too sensitive, as it doesn't affect my job that much, but YMMV. I also love that it has a large, easy to grasp handle, and the length makes it easy to plug in and pull out. Overall, between the light and the ease of use, each outlet I test with this is 1-2 seconds faster than the little 3 light ones. This time saving adds up when I am evaluating 2-3 houses per day in the summer.When I first started buying these, I would get about 4-6 months out of it, using it every day for 50-150 outlets per day. What happens is that the ground pin gets loose and all of the outlets show up as ungrounded and you can no longer test GFCI-rated outlets/circuit breakers. Another problem is that I keep the tester in my tool pouch and constantly pulling it out and putting it back in begins to rub off the words. That isn't a problem for me, as I have the positions memorized, but it defeats the purpose of using this tester because clients can't read it and the pictures don't show the problem.You may be wondering why I still use this product and am giving it 4 stars if it only lasts 4-6 months. Well, after I bought my third one, I figured out some fixes and I have been using my current tester for over 16 months now.1. There is just a little screw holding the ground pin into the tester. After repeated use, the screw will eventually strip out the plastic screw hole and the pin will become loose inside of the unit. Once this happens, the 26 gauge wire connecting the ground pin to the testers computer/processor pulls out and no more ground. This can be fixed after this happens if you have good soldering skills, and you can solder the wire back into place, then superglue the ground pin back into place. This is what I did on my most recent one, and it is still going strong. If/when this one finally breaks, my plan is to purchase a new one and then preemptively superglue the thing right away, which should keep the tester going strong.2. To prevent the words from rubbing off, I treat the housing with a couple coats of clear coat. I tape up the speaker, the GFCI tester and the pins first. It actually looks nicer and shinier when you do this and I have had no issues with the words rubbing off.This might seem a bit drastic, but this is the perfect outlet testing tool for my business, and a little preventative maintenance has gone a long way.

I love how simple this is to use. Simply hold it near a wire to test whether it is hot before working on any electrical or plug it in an outlet to test it and it will tell you exactly what you need to know. The most helpful feature I have found is its ability to test whether an outlet is properly grounded. I wired my basement with this tool and found the ground testing feature to be invaluable. The tool is also durable. I dropped it multiple times from about 6 feet, and it is no worse for the wear.

Sperry actually Grey Bar 100 % stands by the products. Twice replaced it even after two years because letting wore off after thousands of uses in and out of tool holster. . No problem, just send them a photo.Old review : after a few months of daily use the letters are rubbing off making the device not useable. The other problem is a hot ground does not show up. Very easy to use with very clear and bright LED with green indicating correct wiring. The non contact tester is easy to use too.
